ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML

[ggercman]

Hi,
I'm trying to implement Oracle text for searching full text on some tables, and after some time whole web application hangs with exception.:

Message:
Devart.Data.Oracle.OracleException : ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML
Stack Trace:
DbConnectionBase.Open()
OracleConnection.Open()
cv.Open()
DbConnection.OpenAsync(CancellationToken cancellationToken)
--- End of stack trace from previous location where exception was thrown ---


Actual query that I think is responsible for such crash looks like that:
var customersByNameQueryable = context.Persons.FromSqlRaw("SELECT c.* FROM \"Persons\" c WHERE CONTAINS(c.\"FullName\", :p ,1)>0", p);


Before web application crashes, log file also contain such entries:
